i LAMP.

l i Specification of Letters Patent No. 12,520, dated March 13, 1855.

Be it known that I, FREDERICK C. RIDER,

of i the city of Providence, Providence county, and State of Rhode'] Island, have invented certain newand useful improvements in lamps forburning spirit gas, etherealoil, or burning fluid or other analogous preparation having a large percentage of alcohol as itsbase; and I do hereby declare the following to be a full description of the same.

The nature of my invention consists in regulating the flame of a spirit gas burner, I by means of a short tube on the inside of the hollow wick, so that by adjusting, the heightof the tube, by ascrewthe volume of the flame may be increased or diminished at pleasure and at the "same timewithout j the risk of generating toomuch heat in the lamp to be liable to explosion, and thereby in connection withfwire gauze balls in the filler tube, and supply tubes to the wick,

makinga lamp perfectly safe to use, and at the same time equal to-the most splendid Argand lamps in use. But to describe my" invention more particularly I will refer to I the accompanying drawings forming apart of this schedule,the samewletters of reference wherever they occur referring to the same parts. I i

Figure 1, is a profile rlm'of the lamp.

Fig. 2, is a plan view ofthe same. Fig. 3,

is a vertical cutsectionof the same through the line m -m, Fig. 2.

Letter A, is the shell of the lamp, having an ordinary filler tubefBlon the upper side,-

i and in which is a fwire gauze ball C, the

object of which is to prevent the flame,

should any accident occur, from getting into the lamp. From the: lower and inner side of the lamp are two supply tubes, D, D,

communicating with the wick chamber E. In these tubes are also wire gauze balls'F,

F, the object of which isto prevent Lth'e sibility of the flame any accident run-.

ning down by the wick and gaining access to the lamp and cause an explosion.

to fit tightover a tube G, and the two are then forced tightly into the wick chamber, formed ,by the inner wall of the lamp, and

the hollow core of the lamp. This prevents the liability to the flow of the gas, as would be the case if the wick was raised by the spiral, used in Argand lamps where looseness is required. When the elevation of the wick is required it is done by withdrawing the wick tube from the lamp and working the wick up by the fingers, and as the regulator tube H, in the core of the wick regulates the flame, it is not material as to great care or nicety in the length of the wick above the edges of the wick tube. This regulator tube is about an inch long and is secured on a rod I, attached to a screw elevator J, passing through the bottom of the drip cup K, which is screwed to applied to the inner surface of the wick to regulate and control the flame of wick substantially as hereinbefore set forth. a F. o.
